How to Cite a Government Publication:

"Government publications emanate [come] from many sources and so present special problems in bibliographic citation. In general, if you do not know the writer of the document, cite as author the government agency that issued it—that is, state the name of the government first, followed by the name of the agency, using an abbreviation if the context makes it clear" (MLA Handbook for Writers of Research Papers 2009).

Examples:

Government publications can take all different forms: books, magazines, websites, or pamphlets. What is important about them to note is who originally created the material. You will need to cite the state of the government first followed by the department, committee, or agency. You will need to use your judgement here. Look below for examples. The dashes mean the source above has the same author (or same governing body, i.e. New York State, United Nations).
